济南假单胞菌新种的抗生作用

从济南土壤中分离、筛选到Ps 161菌株。该菌株为革兰氏阴性需氧短杆菌，具有激活非蒋异性细胞免疫和特异性体液免疫的功能，能使机体获得免疫应答和免疫反应性。其菌苗对小鼠精原细胞、鼠类移植瘤有显著抑制作用，并增强吡喹酮治疗小鼠血吸虫童虫的作用。能提高人体白细胞和体液免疫功能，对人体癌性胸水和表浅转移癌实体瘤有明显的消除与抑制效果。该菌株的代谢产物对革兰氏阳性细菌有显著抑制作用。 经中国科学院徽生物研究所鉴定，该菌株为一新种，命名为济南假单胞菌(Pseudomonas tnanenses sp. Nov.)。

The antibiotic effect of Pseudomonas jinanensis sp. nov

The Pseudomonas jinanensis has been isolated from soil and screened by antibioticgram assay and spermatogonial assay. It has certain antibiotic properties. The metabolite which has been produced is certainly effective against Staphylococcus aureus and some other positive germs. The preparation of Pseudomonas jinanensis vaccine, namely PJV. It's biological activity on the growth of tumor-bearing mice and the murine spermatogenesis cell. It is considered that enhancement of nonspecific immunologic function of the host might increase the efficacy of praziquantel on schistosomiasis in mice. PJV has certainly produced effectiveness against malignant pleural effusion (effective rate was 76.5%), cancer of lung (effective rate was 58.3%), many solid kinds of cancer (effective rate was 52.1%), and the total effective rate was 64.2%. It could increase the sensitivity of cancer cells to radiation. PJV could stimulate the animal (rabbit) to develop specific antibody. PJV might belong to the class of immunomodulating agents.
